- 30 - Abstract of the Disclosure The invention relates to a grounded or isolated water- based plural component system for the electrostatic application of water-based paint. The invention enables the use of traditional color change systems during use of electrostatic spray devices. The invention includes an electrically isolated electrically less-conductive component fluid-flow course and an electrically-grounded electrically more-conductive component fluid-flow course. The electrically more-conductive component fluid-flow course may be additionally electrically isolated at the preference of an operator. The invention includes an electrostatic spray gun device, a mixing means positioned proximal to the electrostatic spray gun, and a first conduit which holds alternating segments of electrically more-conductive component and electrically less-conductive component. The alternating segments of electrically less-conductive component and electrically more-conductive component function in series to additively provide a combined resistance which electrically blocks the high-voltage potential generated at the electrostatic spray gun. This, in turn, effectively isolates the electrically more-conductive component fluid-flow course and electrically less-conductive fluid-flow course from the high-voltage potentials, which significantly improves the safety of an electrostatic spray gun used with water-based paints, while simultaneously permitting the use of a standard color change system.
